When a PR gets merged it looks like it lost all the information regarding the commit and the changes made by that PR. I believe it'd be useful to still see the changes there, like in a regular GitHub project. Also I believe we are going to be losing context and information compared to the bugzilla workflow. In a complex patch that might have several review iterations and that might change the design or whatever, you'll have no way to see previous versions of the patch, or understand the review comments as you won't have the whole context anymore.
This is not intentional, and will stop happening once GitHub becomes the source of truth. I couldn't find an existing bug for this though.

Good to know, I guess there's nothing to do until the GitHub transition is complete. Feel free to close this or keep it open for tracking purpose, as you prefer.
